En este sentido, el tratamiento de aguas residuales que incorpore la remoción de iones metálicos es causa de múltiples investigaciones a nivel mundial. El objetivo de esta investigación fue determinar la capacidad de remoción del plomo (Pb) presente en aguas sintéticas y la intensidad de adsorción del helecho Azolla caroliniana por este metal. Se utilizó un espectrofotómetro de absorción atómica para determinar la concentración del plomo adsorbido. A partir del gráfico de isotermas de Langmuir se determinó que, para los 4 reactores utilizados, el tipo de sistema isotérmico era desfavorable para esta isoterma (RL’s mayor a 1). Por su parte, las gráficas de las isotermas de Freundlich para los 4 reactores permitieron establecer los modelos lineales del comportamiento cinético de la adsorción de plomo mediante Azolla caroliniana, obteniendo el mejor R2 y la mayor intensidad de adsorción (n) de Pb (0,122) para el reactor D (30 ppm de Pb).Universidad de Lima2022-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistas.ulima.edu.pe/index.php/Ingenieria_industrial/article/view/579210.26439/ing.ind2022.n42.5792Ingeniería Industrial; No. 42 (2022); 99-114Ingeniería Industrial; Núm. 42 (2022); 99-1142523-63261025-992910.26439/ing.ind2022.n42reponame:Revistas - Universidad de Limainstname:Universidad de Limainstacron:ULIMAspahttps://revistas.ulima.edu.pe/index.php/Ingenieria_industrial/article/view/5792/5682https://revistas.ulima.edu.pe/index.php/Ingenieria_industrial/article/view/5792/6515https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessoai:revistas.ulima.edu.pe:article/57922024-10-14T14:41:02Z |
